ENOCH OHNSTRAND, OF MOHAWK, NEW CAMBRIDGE, MASSACHUSETTS,

Laren.

To all whom t may concern Be itknown that L'ENooH OHNsrRAND, citizen o f the United States, and resident of Mohawk, in the county of Herkimer and State offNew York, have inventednew and usefulV Improvements in Latches, of which the following is aspecification.

This invention relates to a new and improved drawer pull and latch and more speto device of this character in which the latch is operated by the movement of the pull handle.

In the use of drawers in desks or filing cabinets Aor in connection with cabinet or other closureslof similar types it is'often desirable to provide means for'latching the closure or drawer in' place.v This isparticularly true in the case of drawers which are adapted to be drawn outward endwise in either direction fromY a file stack or desk pedestal.` Iny closing such drawers there is a tendency for the drawer, due to its inertia andthe momentum acquired during the closing movement, to pass beyond its central-or closed position and to extend outward upon the opposite side of the stack or pedestal.

The latch to beof utility in such construction must permit the drawer to be drawn voutward from the oppositey end than that occupied by the latch. `The latch should be capable of use in pairs, one upon each end "of the latch uponthe'end toward which the drawer is to be moved should be suiiicient to release the drawer for movement.

' It is an object of my invention to provide a combined latch and pull of the character described which is automatic in its action in that the latch is released by the normal actuation of the pullhandle. It is also an object to provide a device which is simple in construction, and which is relatively inexpensive to manufacture. Other and further objects will appear as the description proceeds.

l have illust-rated a preferred embodiment of my invention in the accompanying drawing in which; e

drawer and the use of which comprises but few parts The latchy comprises the= back member 6,V

outwardly to house the: latch mechanism and is cut away'at the sides to permit introduction of the pull handle 8 and the members 13 on the back member 6.

The `pull handle 8 is a solid loop of metal substantially circular in cross section as shown. At the point 14 inside the face mem.

ber. the lpull handle is cut away andthe remaining portion extendedy oppositely somewhat at 15. The rock shaft 9 is carried by the pin 16, the ends of the latter being upset to retain it in place in the face member. The rock shafty 9 is provided with 'the cam li1g17 adapted to coact with the adjacent Vportion of the pull handle and is also provided with the lift iinger'lS adapted to lift the bolt.

VThe bolt" 10 is cut away at 19 to receive they lift finger 18. The bottom end of the boltisrearwardly beveled at 20.

The catch 21 is attachedto theiixed portion 22 of the desk or cabinetby the bolts 23. This catch engages'the bolt 10 aslshown in Figs. 1 andl2. Y

The latch may be readily assembled or dismantled, removal ofthe 'bolts y12 permittingthe face-member to be disengaged from the back member and the bolt and pull handle may then both be removed.

As shown in Figs. 1 and 2 the engagement of thebolt 10 with the catch 21'efl'ectually maintains thefd-rawer closed. Pulling upon the pull handle S in opening the drawer swings that handle to the position shown in Fig. 3, the engagement between the cam portion of the handle and the cam lug 17 on the rock shaft serving to rotate that shaft suiiiciently to cause the lift finger 18 to lift the bolt out of engagement with the catch 21. ln closing the drawer the beveled surface 20 on the bolt 10 engages the lip of the catch 21 and serves to lift the bolt over the catch. The cut away portion 19 of the bolt is of suiiicient height to permit this lift of the bolt without causing any movement of the rock shaft or pull handle.

In the use of this type of latch with a Vclosed the bolt ofthis latch upon attached, one upon its central or normal position.

drawer of the type adapted to be drawn out in either direction, a* pair of latches will be. each end of the drawer.v

Thelatch upon the end of the drawer which is to be drawn outward will operate in the manner which has been described. The bolt of theiatch upon the opposite end will be lifted bymeans of its beveled cam surface 20 which will ride up over the fixed portion 22 of the desk or cabinet, the portion 19 of 'the bolt permitting the handle to remain stationary. lVhen the drawer is again the opposite endwill drop into its catch and it will be impossible to push the drawer in beyond Y It will be possible to pull the drawer out in either direction by pulling upon the corresponding latch but if the drawer is closed simply by "giving it a push the opposite latchwill positively stop it at the proper point.
